In 1997, GUM participated in the 'International Young Conductor's Competition of the Herbert von Karajan Foundation, in which he was chosen as one of top finalists and was given an opportunity to conduct the Berlin Philharmonic Orchestra. Thereafter, he conducted the Berlin Radio Symphonic Orchester and the Rundfunkorchester Hannover des NDR (Hanover Radio Symphony Orchestra).
Since returning home in 1980, he was appointed Conductor of the Korea Philharmonic Orchestra (currently KBS Symphony Orchestra) and has enriched the repertoire by developing music programs for the orchestra, which featured a number of talented soloists, domestic and foreign.
Since late 1980s, GUM has been active in organizing music programs among musicians of European countries and Korea, which led to his appointment in 1987 as Music Director of the European Masters Orchestra, an assembly of many talented musicians from various renowned European orchestras including the Berlin Philharmonic, the London Symphony Orchestra, the Vienna Philharmonic, and the National Radio-France Orchestra. In 1988, the EMO performed in Zagreb (Yugoslavia), Budapest, and many cities in Korea. During that period, he regularly appeared with the Moscow Chamber Orchestra with which he toured Finland(1991), Berlin(1992), and Korea(1993).
GUM's list of guest conducting engagements in North America includes Prague's Radio Symphony Orchestra, the Sacramento Symphony Orchestra, the Alsaska Symphony Orchestra, the Zagreb Philharmonic Orchestra, the Leningrad Symphony Orchestra, the Leningrad Philharmonic Orchestra, and the Moscow Philharmonic. From 1992 to 1999, Nanse served as Music Director of the Suwon Symphony Orchestra in Korea and Principal Conductor of the Deutsche Kammer Orchestra in Frankfurt, Germany.
Since 1999, GUM has been primarily engaged in the activities of the EURO-ASIAN PHILHARMONIC ORCHESTRA. Under his dynamic leadership, the Orchestra has rapidly gained prominence in the national music scene through innovative educational programs that appeal to music lovers of all ages. GUM is also currently serving on the music faculty of KyungHee University, Seoul, Korea.
Subsequently, the EURO-ASIAN Philharmonic Orchestra (EAPO) presented its inaugural concert in August 1998 at Sejong Center, Seoul, and subsequently completed successfully a concert tour throughout six major cities in Korea.
The years of 1999-2000 were formative years for the EAPO as it performed Beethoven's 9th Symphony at a GALA Concert at POSCO Atrium on New Year's Day, and presented a complete Beethoven Symphonies cycle at the same auditorium in 2000. The EAPO was invited to perform two concerts commemorating the opening and closing ceremonies of ASEM (Asia-Europe Meeting) in September 2000.
Since its inaugural concert, the EAPO accompanied a number of the world's most acclaimed soloists. The EAPO will add one additional meaningful concert series as its regular activity by presenting music programs for the Youth at Sejong Center.
Since 2001, the EAPO has been moving diligently towards a leap under the new motto of 'a venture orchestra.' The number of performances has increased from 60-70 times to over 80 times in 2002. Not only are we expanding the number and programs of the performances, but we are also preparing to advance into new areas such as recording and DVD production.
Cooperation with companies through the medium of culture, which we have promoted since our establishment, is regarded as a model in this area. Cooperation with Samsung Electronics since 2001, and with Cheil Jedang since 2002, are recognized as exemplary models of cooperation that promotes the mutual development of industries and art groups.
Under the artistic supervision of Music Director, Nanse GUM, the EAPO will continue to offer music for every taste and audience including the great classical masterworks with some of the world's outstanding soloists.
The EAPO is permanently stationed at the National Library of Korea, and is holding library concerts more than 10 times a year for intellectual audiences, jointly with the library.
